A touch of red mud in the red mud workshop, Princess Wencheng's royal red mud foundation.

Princess Wencheng Royal Red Mud Foundation 1300 years ago In the Tang Dynasty 1300 years ago, Princess Wencheng was deeply appreciated by Emperor Taizong because of her youth, beauty, elegant temperament, dignified appearance and sensible knowledge, and was regarded as a national color and a pearl of a generation. Princess Wencheng, as pure as ice and pure as jade, has served the country all her life and lived up to her mission. She married Tubo (Tibet) not far from Chang 'an, and married Songzan Gambu, the king of Tubo, which promoted the friendship between the two peoples for generations.

Because the Qinghai-Tibet Plateau is high in altitude and the air is thin, the ultraviolet rays of the sun are particularly fierce. People who enter Tibet from the plain will be as thick as "plateau red" in a few days (the skin protects itself from ultraviolet rays).

After Princess Wencheng entered Tibet, she hired Songzan Gambu, a Tibetan king from the Qinghai-Tibet Plateau, to meet Princess Wencheng. She fell in love with her at once. Princess Wencheng from the Central Plains is graceful and elegant, and is loved by one hundred Tubo kings. However, in the face of Songzan Ganbu, which is tall, strong, brave and full of lofty sentiments, Princess Wencheng felt a little bit of joy and tenderness in her heart.

Princess Wencheng's skin is a little purple because she wants to know the Tibetans around her with Songzan Gambu, the king of Tubo. Princess Wencheng began to worry about her skin. The careful Princess Wencheng found that the young Tibetan children were childlike. In order to prevent the sun, they hoe some red mud and apply it to their faces during the day to prevent ultraviolet rays. At night, they painted red mud. Therefore, Princess Wencheng thought that the plateau was poor in material resources, and there was neither pearl powder nor rouge. Why not put some red mud on your face like Tibetan children? In order to be decent and generous, I can't paint too thick and make people laugh like a child. Therefore, Princess Wencheng painted red mud on her face from time to time at night and a thin layer of red mud during the day to protect herself from the sun. Soon, Princess Wencheng's skin became white and tender again. Princess Wencheng returned to her old smiling face. In order to protect the skin of Tibetan people, Princess Wencheng immediately proposed to Songzan Gambu to promote it, so that everyone could paint red mud on their faces. In addition, in order to remove the gravel from the red mud on the Qinghai-Tibet Plateau, Princess Wencheng specially chiseled a corner in the palace, allowing the children to carry a basket of red mud with a stone mill, and craftsmen could grind the coarse mud to make a foundation. Later, Princess Wencheng gave this red mud processing factory a poetic name-Red Mud Workshop. Therefore, the ancient Tibetans were also called Hongqiang.

Princess Wencheng's beauty, gentleness and warmth have already melted in the red mud of the Qinghai-Tibet Plateau. In order to commemorate her from generation to generation, the Tibetan people specially built Princess Wencheng Temple with red mud, and the incense continued. Since then, with a touch of red mud princess's smile, the skin care method of red mud foundation has been widely circulated and famous all over the world.
